Abstract
This disclosure is related to post processing steps for integrating of micro devices into system (receiver) substrate or improving the performance of the micro devices after transfer. Post processing steps for additional structure such as reflective layers, fillers, black matrix or other layers may be used to improve the out coupling or confining of the generated LED light. In another example, dielectric and metallic layers may be used to integrate an electro-optical thin film device into the system substrate with the transferred micro devices. In another example, color conversion layers are integrated into the system substrate to create different output from the micro devices.
